Cosmetic and dermatological compositions containing aminoalcohol derivatives containing a urea functional group and uses thereof

ABSTRACT

The invention relates to the use of aminoalcohol derivatives containing a urea functional group corresponding to the following formula: ##STR1## in which: R 1  represents a linear or branched, saturated or unsaturated alkyl radical having from 8 to 22 carbon atoms; R 2  represents a hydrogen atom or a linear or branched, saturated alkyl radical having from 1 to 6 carbon atoms; R 3  represents a linear or branched, monohydroxylated or polyhydroxylated, saturated alkyl group having from 1 to 10 carbon atoms, in and for the preparation of cosmetic or dermatological compositions. These compounds are used in particular as moisturizing agents in care products for the skin or as conditioning agents in hair products.

The present invention relates to the use of aminoalcohol derivatives containing a urea functional group in and for the preparation of cosmetic or dermatological compositions, in particular to their use as moisturizing agents in care products for the skin or as conditioning agents in hair products.

A number of aminoalcohol compounds containing a urea functional group are known in the state of the art. Some have been described in particular in U.S. Pat. No. 3,135,790 and are used as emulsifying agents in paint or lacquer formulations or as synthetic intermediates. Others, such as those described in German Patent DE 1,125,905, in particular N-methyl-N-(2,3,4,5,6-pentahydroxy-n-hexyl)-N'-n-octylurea, are used as textile additives, washing agents or crosslinking agents or as emulsifiers. Some aminoalcohol derivatives containing a urea functional group are used in U.S. Pat. No. 2,891,944 for their insecticidal properties. A description has also been given, in the article J. Med. Chem., 31(4), 858-863, 1988, for its activity with respect to certain cancerous cells, of 3-(3-octadecylureido)-1,2-propanediol.

The inventors have discovered, surprisingly, that specific aminoalcohol derivatives containing a urea functional group, the structure of which will be defined hereinbelow, exhibited advantageous cosmetic properties, in particular moisturizing properties with respect to the skin.

This is because it was found that, by applying these products on the skin, it is possible to decrease the water loss thereof and/or to increase the attachment of water in the stratum corneum. These compounds can thus be used as moisturizing agents, in particular for human skin.

They make it possible to retain or to restore the flexibility of the skin, its elasticity, its resistance to the movement of the body and its function of barrier to the entry of toxic substances. They can thus be used in care products for dry skin or skin predisposed towards drying.

These compounds unexpectedly exhibit a very much greater barrier activity with respect to permeability to water on the skin than their carbamate or amide homologues known in cosmetics for their moisturizing properties.

The inventors have also discovered, surprisingly, that the aminoalcohol derivatives containing a urea functional group according to the invention, used in hair compositions, confer a particularly soft feel on hair and facilitate the disentangling thereof. They can be used as hair conditioning agents.

The main subject of the invention thus relates to the use of aminoalcohol derivatives containing a urea functional group, which will be defined subsequently, in and for the preparation of cosmetic or dermatological compositions.

Another subject of the invention relates to the cosmetic or dermatological compositions containing these aminoalcohol derivatives containing a urea functional group.

Another subject of the invention thus relates to the use of these aminoalcohol derivatives containing a urea functional group as moisturizing agents in and for the preparation of compositions for the care of the skin.

Another subject of the invention thus relates to the use of these aminoalcohol derivatives containing a urea functional group as hair conditioning agents in and for the preparation of hair compositions.

Other subjects will become apparent in the light of the description and examples which follow.

The aminoalcohol derivatives containing a urea functional group in accordance with the invention correspond to the following general formula (I): ##STR2## in which: R₁ represents a linear or branched, saturated or unsaturated alkyl radical having from 8 to 22 carbon atoms;

The reaction mixture was kept stirring at reflux for 4 hours. The reaction mixture was cooled with an ice bath and the precipitate was then filtered off. It was washed with 500 cm³ of water and then dried. 49 g (80% yield) of N-dodecylaminocarbonyl-N-methyl-D-glucamine were obtained in the form of a white powder.

47 g of 1-N-(octylaminocarbonyl)imidazole and 42 g of N-methyl-D-glucamine were suspended in 300 cm³ of methanol under an inert atmosphere. The reaction mixture was maintained at reflux with stirring for 3 hours. Cooling was carried out with an ice bath and then the precipitate is filtered off. It was recrystallized from 300 cm³ of ethanol. 40 g (55% yield) of N-octylaminocarbonyl-N-methyl-D-glucamine were obtained in the form of a white powder.

Measurement of the imperceptible water loss (IWL)

This measurement was carried out using an evaporimeter (Servomed) which quantitatively determines the evaporation of water, that is transportation of water by diffusion, from a stratum corneum sample which seals a cylindrical capsule containing water, the whole assembly being placed in a chamber with controlled relative temperature and controlled relative humidity.

Sensors made it possible to measure the partial vapour pressure of water at two points situated at different distances from the sample.

The partial vapour pressure of water gradient between the two points was thus determined and therefore the degree of evaporation in accordance with Fick's law.

This measurement is carried out for:

a) N-dodecylaminocarbonyl-N-methyl-D-glucamine (compound of Example 1);

b) N-dodecanoyl-N-methyl-D-glucamine, amide homologue of the compound of Example 1, known to be a moisturizing agent, which will be called Reference A;

c) N-dodecyloxycarbonyl-N-methyl-D-glucamine, carbamate homologue of the compound of Example 1, known to be a moisturizing agent, which will be called Reference B.

The compounds were prepared in the proportion of 1% in a dichloromethane/methanol (2/1 v/v) mixture and then applied on pieces of delipidated stratum corneum.

The imperceptible water loss (IWL) for each compound was measured 20 hours after application.

The following results are obtained:

It was thus found that the application of the compound according to the invention makes it possible to reduce the evaporation of the water contained in the stratum corneum to a greater extent, in comparison with its amide and carbamate homologues.
